ToBAoco PIPE.

Application led 'July 22,

Be it known that'I, FRANK T. HrrEs, a citizen of the United States, residing at the city of St. Louis, Missouri, have invented a new and useful Tobacco Pipe, of which the following is a specification.

This invention relates to tobacco pipes.-

An object of the invention is to provide a pipe having a. stem equippedl with a device of lnovel and improved construction to prevent the stem from becoming clogged.

Another object of the invention is to provide a tobacco pipe having a stem provided with a smoke passage opening into the bowl of the pipes, and also provided with an inclined passage opening into the i smoke kpassage and a groove at the outer end of the inclined passage, in combination with a slide for sealing the groove and the inclined passage therefrom, and a wire or rod in connection with the slide extending through the inclined passage and'movable by the slide to open the smoke passage into the bowl to prevent clogging of the smoke passage.

In the drawings- Fig. 1 is a planvview of my improved pipe with parts in normal position. y

Fig.`r2 is aplan view of the pipe showing a rod or wire projected into the bowl of the pipe by the slide.

Fig. 3v is a sectional view of the pipe showing the construction and arrangement thereof.

The pipe includes the usual bowl 1 having a stem 2 in connection therewith provided with a smoke passage 3 opening into the bottom of the bowl.

An inclined passage or hole 4 is formed in the stem 2 beginning at a point near the opening of the passage 3 into the bowl and extending obliquely upwardly and outwardly into a groove 5 in the upper side of the stem. The groove 5 has its bottom wall inclined in continuation of the bottomwall of the inclined hole or passage 4. The outer end of the groove 5 forms an abrupt shoulder 6. Y

A rod or Wire 7 is mounted in the groove 5 and in the hole or'passage- 4 and, in no-rmal position of parts, has its inner end above the smoke passage 3. The rod or wire 7 rests upon the bottom wall of the oove 5 and on its outer endl is formed with anV upward extension 8 whiclr engages in a hole in a knob 9 on the outer end of a slide 10.

1922. Serial No. 576,753.

Preferably the extension 8 is slidable 'in theV hole in the Vknob 9 to permit proper relative movement of the parts when the slide 10 is moved toward the bowl of the pipe and Y then to its closed position Aas shown in Figs. 1 and 3, without straining the rod or the f slide.

The slide is held within a .guide compris-V` ing. a pair of bands 11 encircling and rigidly Vsecured to the pipe stem and .integrally united by a plate portion 12. The outer band 11 is formed with' an extension 13 upon which the outer end of the slide rests when the slide is in its outer or closed position. Y

A slot 14 is formed through the plate 12 and through portions of the bands 11 registering with the groove 5 to accommodate the extension 8 of the wire or rod 7. The slide 'l0 operatesunder turned-over extensions 15 tact of the extension 8 with the end wall of the groove 5. f

The extent of movementof the slide and of the wire or rod 7 is suiiicient to cause the inner end oi therwire or rod to enter the bowl of the pipe when the slide is pushed inwardly; and when the slide is moved outwardly the wire or rod 7 is entirely within.

thebowl or passage 4 and does not in any way obstruct the smoke passage 8 through the pipe stem. The slide and the wire or rod 7 cooperate to form a seal for the opening from the pipe passage so that there will be no interference with the proper functioning of the pipe when in use.

- The specific construction and arrangement may be varied without departure from the nature and principle of theinvention..

I do not restrict myself unessentially, but what I claim and desire to secure by Letters Patent is 1. Inra tobacco pipe, a bowl, a stem in connection with the bowl having a smoke passage opening therethrough from the bowl and having an inclined passage from the smoke passage toward one side of the stem,

and a groove in said side of the stem into which the inclined passage opens7 a band encircling the Stem and being rigid therewith and having a slot therethrough opening into said groove, a longitudinally movable slide for closing said groove, means in connection With said band preventing said slide from turning around the stem and guiding said slide in its longitudinal movements, and a wire in connection with said slide extending through said inclined passage.

tobacco pipe comprising a bowl, a stein in connection with the bowl having a smoke passage and an inclined passage open-- ing into the smoke adjacent to the bowl, a slide movable longitudinalljyv on the stem for closing the inelined passage, a device supported by the stein preventing said slide from turning around the stem and guiding the slide in its longitudinal movements, and a Wire mounted in said inclined passageand having its outer end engaging said slide. l

3. A tobacco pipe comprising a bowl, a stem in connection With the bowl having a smoke passage and an inclined passage opening into the smoke passage adjacent to the bowl, a slide movable longitudinally on the stem for closing the inclined-passage, a device supported by the stein preventing said slide from turningl around the' stem and guiding the slide in its longitudinal movements, a knob in connection with said slide vhaving a hole in its inner side and a Awire mounted in said inclined passage having an outwardly beni` portion at its outer end engaging insaid hole. ,y
